BIS Certification in India
The complete guide to ISI Mark, CRS, and Scheme X — the three BIS certification schemes that govern hundreds of product categories sold in India.
What is BIS Certification?
The Bureau of Indian Standards (BIS) is India's national standards body, operating under the Ministry of Consumer Affairs. BIS certification is mandatory for hundreds of product categories — from mobile phones and LED lights to steel and food products — sold or manufactured in India.
Mandatory BIS certification is enforced through Quality Control Orders (QCOs) issued by the central government. A product listed in a QCO cannot legally be sold in India without the appropriate BIS certification. Violations attract penalties, seizure of goods, and criminal liability under the BIS Act 2016.
BIS operates three primary certification schemes: CRS (Compulsory Registration Scheme), ISI Mark, and Scheme X. The applicable scheme depends on the product category and whether the manufacturer is domestic or foreign.

|---|---|---|---|
| Product scope | Electronics, IT, appliances (60+ QCO categories) | Electrical, cement, steel, food & other regulated goods | Heavy machinery, industrial equipment (OTR) |
| Who can apply | Domestic & foreign manufacturers | Domestic manufacturers (factory-based) | Domestic manufacturers |
| Factory inspection | Not required (most products) | Required | Required |
| Validity | 2 years | Licence-based (renewable) | 3–6 years |
| Typical timeline | 3–8 weeks | 2–3 months | 3–6 months |
| Registration unit | Brand + manufacturer + product | Factory + product category | Factory + product |
How BIS CRS Certification Works
Testing at BIS-Approved Lab
Product samples are tested at a BIS-empanelled laboratory in India against the applicable Indian Standard. Overseas test reports are not accepted for CRS.
BIS Application & Document Review
The application, test report, and supporting documents (brand authorization, manufacturer details, AIR appointment for foreign manufacturers) are submitted and reviewed by BIS authorities.
Granting of Registration (R-No.)
Upon successful evaluation, BIS issues a unique Registration Number (R-No.) for the specific brand–manufacturer–product combination. The CRS label with this R-No. must appear on the product.
Frequently Asked Questions
What is BIS certification and why is it required in India?
BIS (Bureau of Indian Standards) certification is a mandatory quality mark required for hundreds of product categories sold in India. It ensures products meet Indian safety and quality standards. The three main schemes are CRS (electronics/IT), ISI Mark (general regulated products), and Scheme X (industrial/machinery).
What is the difference between BIS CRS, ISI Mark, and Scheme X?
BIS CRS (Compulsory Registration Scheme) applies to electronics, IT products, and appliances listed under Quality Control Orders — registration is granted per product-brand-manufacturer combination and is valid for 2 years. ISI Mark applies to products that must carry the Standard Mark under BIS licensing schemes — it requires a factory inspection and is tied to the manufacturing facility. Scheme X (the Omnibus Technical Regulation) applies to heavy machinery, industrial equipment, and products not covered under CRS or ISI.
Who needs BIS certification — Indian manufacturers only, or foreign ones too?
Both Indian and foreign manufacturers need BIS certification for products sold in India. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) to apply on their behalf. The AIR is responsible for the application, testing coordination, and ongoing compliance.
How long does BIS certification take?
BIS CRS typically takes 3 weeks for non-border-sharing countries and 7–8 weeks for border-sharing or geopolitically sensitive nations. ISI Mark certification takes 2–3 months including factory inspection. Scheme X timelines vary by product category.
What happens if a product is sold without BIS certification where it is mandatory?
Selling products without mandatory BIS certification can result in seizure of goods, cancellation of import licenses, significant monetary penalties, and criminal liability under the BIS Act 2016 and the relevant Quality Control Order.
